Without getting into the complex details of why i would like this. I would like to be able to have access to the page request string before the page is rendered (not before any interceptors).

i thought this would be in

FacesContext.getCurrentInstance().getExternalContext().getRequestHeaderMap()

but apparently its not because i printed the keys with something like

       Map<String, String[]> request = FacesContext.getCurrentInstance().getExternalContext().getRequestHeaderValuesMap();
          Iterator iterator = request.keySet().iterator();  
         while (iterator.hasNext()) {  
            String key = iterator.next().toString();  
            String value = request.get(key).toString();  
            System.out.println(key + " " + value);  
         }  

or something like that. the referer key was close... but that is the page the request came from not where we are going.
can anyone give me a hint as to where to look? help would be greatly appreciated.
